When the plague entered the port of Gotham it did not receive the attention it deserved, and with the movement of large numbers of outsiders, especially seafarers and logisticians, the plague began to spread rapidly. Fortunately, because there are too many Chinese Imperial submarines on the stormy ocean, shipping is no longer very prosperous, and with the loss of the Chicago industrial area and the Chinese Imperial Army, more and more materials produced by the Boston Empire have been used to protect the homeland. Even the airships that had been busy over the stormy ocean were basically cut off, so that the plague did not spread to the western continent.

The epidemic began to get worse and worse, even in Boston, dozens of people died every day, at this time Washington III and Prime Minister Bauer finally found out that something was wrong, and they quickly issued an order across the country, requiring all localities to start quarantining patients, strictly guarding against a suspected case, in order to prevent the plague from continuing to spread, and at the same time, the whole country launched a rodent eradication campaign, hoping to cut off the spread of the plague from the source.

Under the rapid spread of the plague, Boston began to gradually become chaotic, and many people began to hide in despair, but there were plague outbreaks everywhere, and they could escape anywhere. Now they can only run around in despair, or flee into the mountains, or into the desert, until one day they also fall to the ground in black and purple.

Boston gradually began to be chaotic, and even the garrisons in the Wudalianhu area were affected, and the morale of the garrisons in many places was fluctuating, their combat effectiveness was greatly reduced, and there was even a phenomenon of desertion, but only because of the strong pressure of Marshal Pershing, there was no phenomenon of disobeying commands, but their will to fight was seriously shaken.

Taking advantage of this opportunity, the twelve White Mountain-class river gunboats that had just been delivered to the troops immediately set sail and headed for Travers City, where the shipyard of the Boston Army was located. Although the Boston army does not have the perverted radar system and high-altitude reconnaissance planes of the Chinese army, they can send a large number of reconnaissance ships and use them to carry out early warning.

After seeing the Chinese gunboat formation, they quickly passed the information back to headquarters, and although the Chinese formation that found these reconnaissance boats quickly sank them, the news had already been transmitted back by the wolf smoke, a substitute for the radio failure, and the Boston fleet stationed at the base was already prepared.

When Marshal Pershing was overjoyed when he received the news of the attack, he immediately ordered the entire fleet to attack and try to encircle and annihilate this small Chinese fleet. Twenty-six Lake Mead-class gunboats were ordered to set sail and meet the Chinese fleet in battle formation.

Seeing that the sneak attack failed, the Chinese fleet also set up a battle formation to meet it. Fifteen kilometers away, the naval guns on the two turrets of the Chinese gunboats began to wield. Due to the caliber of 122 millimeters, and the advanced propellant charge of the Chinese artillery shells, the firing range was 20% higher than that of the Axis powers, they could attack the enemy first.

Shells fell around the Bostonians' gunboats, causing churning waves, and the Bostonians immediately rushed forward at full speed. There was not much difference in the range of the artillery of the two sides, and soon the one and five mm guns of the Bostons also began shelling.

The Bostonian river gunboat was relatively long and narrow, and its bow had only one main gun, while the Chinese gunboats were slightly shorter and thicker, and the bow was knapsack with two turrets, both of which were the turrets of the Grizzly 4 tank, and they were equipped with 122 mm main guns, which were more powerful than the other side.

Both sides could only use the bow and main guns to bombard head-on, and although the number of gunboats of the Chinese army was small, the number of artillery was much higher, so the effect of the artillery battle on both sides was half a pound and eight taels, and no one took too much advantage. At this moment, two large groups of planes appeared in the sky, and after the battle on the water began, both sides sent their own mixed groups.

The Golden Eagle 5 fighters rushed forward quickly, passing their own fleet, and they used the on-board radar to lock on to the opposing fighters, and immediately began to launch air-to-air missiles. Those Boston Air Force pilots saw the air-to-air missiles coming head-on, and many of them accelerated out of the formation. In the narrow space in the formation, they quickly evaded the attack of the missiles with a large overload maneuver, but these Boston pilots did not expect that because the speed of the missiles exceeded the speed of the F104 fighters too much, they were still shot down without suspense, the difference was that they were the fastest ones to die because they rushed too fast.

Faced with a large number of missiles, the Boston Air Force had no choice but to break up and launch attacks from all directions to distract the attention of the Chinese Air Force, while those B25 tactical bombers rushed to the Chinese Army's lake fleet at a low altitude and against the water.

Seeing the opposing bombers approaching their warships, the pilots who flew the old Golden Eagle 4B fighters quit. They were a little powerless against the F104 fighters, but they were still very easy to deal with the large, slow-moving propeller bombers.

Seeing that the Golden Eagle 5 fighter and the F104 fighter were fighting hotly, they immediately turned around and rushed towards the B25 bombers who were ready to drop their altitude to drop bombs. How a bomber powered by two propeller engines was a match for jet fighters, and the Chinese Air Force fighters, who launched a surprise attack at extremely high speeds, pounced on their targets.

The large-caliber cannon fired continuously, and the B25 bombers soon lost their bare bombs, and they all made serpentine maneuvers against the water, hoping to avoid the attack of the opposing fighters. A handful of fighters mixed in with the bomber force were at full speed to meet the rushing Golden Eagle 4B fighters, while the Chinese pilots ignored the enemy F104 fighters, and they got close to the Boston bombers, using their huge fuselage to resist the invasion of their opponents.

Seeing that those Chinese army pilots used those B25 bombers to cover with superb flying skills, they started a war of movement, and soon achieved good results, and more than a dozen Boston bombers were shot down and crashed on the lake. Seeing that the target they were protecting was shot down, those Boston fighters were in a hurry, and they immediately accelerated to get close to the bombers, and the fighters of the Chinese Air Force surrounded the bomber group, playing a dangerous maneuver like a veneer dance.

Fierce fighting broke out in the air between the two sides, and one plane after another crashed on the lake, stirring up huge waves that were more lively than the artillery battle between the two sides. The Chinese army's advanced planes and large numbers caused the Boston Air Force to retreat again and again, and after losing more than 100 fighters and more than 30 bombers, they had no choice but to retreat.

The Boston Air Force was forced to retreat, which hurt the Boston fleet fighting the lake, and they also wanted to retreat with the group, but those White Mountain-class gunboats bit them and refused to relax at all, so that these Boston gunboats could not retreat at all.

Seeing that their gunboats were holding back the other side, a large group of albatross dive bombers rushed straight down against the Boston gunboats, and the terrible screams filled the sky, and one dive bomber after another charged the poor Boston gunboats at a wide angle of more than 70 degrees, sinking them one by one in the lake, and only half an hour later, the Boston Wudalian Fleet was completely reimbursed.

After destroying the Boston fleet, the remaining eight Baishan-class gunboats of the Chinese army rushed towards Travers City at full speed. Hearing the air force's report, Pershing knew that something was wrong, not only would the fleet be completely annihilated, but even the shipyard near the lake would be in danger. Although it was known that the other party had arrived, the shipyard was desperate to evacuate at all, especially the dozen or so gunboats that were still under construction, and they could not move.

The Bostonians had not yet figured out a good way to transfer the shipyard, and the Chinese army's Wudalianhu fleet had already arrived nearby. The dense bombardment of 122 mm guns began, and a large number of albatross dive bombers took on auxiliary attack missions, and they rushed to various key areas of the town, carrying out a frenzied bombing, some of which took care of several airfields in the suburbs, causing considerable losses to the Axis air forces.

Although all the planes took to the skies to avoid the air attack on the airfield after hearing the alarm, the ground crews and equipment were not able to move and were all destroyed by the bombers. The plague epidemic had greatly reduced the combat effectiveness of the Boston army, and Marshal Pershing could do nothing about it. After taking control of the entire lake, the Chinese army began to rely on Baishan-class gunboats and lake transport ships to attack everywhere and flexibly attack the Boston garrison along the lake.

The Boston garrison soon became unbearable, and in the end they had to leave behind the soldiers infected with the plague and the incurable wounded to retreat. This was also a decision made in desperation, in the Boston Empire, which lacked medical treatment, it was difficult to survive the plague and serious injuries, so it was better to leave them to the Chinese army. Bound by international conventions, it is believed that the other side will treat them, even if they are destined to enter the prisoner camp, it can be regarded as retaining some prime-age labor for the Boston Empire.

What Marshal Pershing never expected was that before Fang Ruijun attacked the New World, he gave Su Zhizhen a secret order, asking him to consume the vitality of the Boston Empire as much as possible and reduce its population during the battle. Su Zhizhen admires Fang Ruijun's long-term vision, and in order to reduce strong enemies for the country and the nation, Su Zhizhen is also very willing to carry out this order.

Because of this order, Su Zhizhen issued an order to kill all the people in Boston after they also began to resist, and it was also because of this order that when Gao Jun wanted to attack with biological weapons, Su Zhizhen helped him cover up.

Su Zhizhen really wants to eliminate more Bostonians, but it is a matter of national reputation, and this kind of thing cannot be done too obviously, otherwise it will be easy to be spurned by others. This is the case of these Boston wounded and sick, if he accepts these people and does not treat them and let them die, it is easy for the world to criticize, so when Su Zhizhen saw this situation from the satellite photos that came, he chose to pretend to be deaf and dumb.
